I have the car right now, but I'm dropping it off at Automaster today for it's final tune next week. I do not have any vids as of yet, but when I get back I will surely do a nice vid. At idle, you can hardly tell I have cams.....the idle is rock solid. At full throttle, you can hardly hear yourself over the whine of the turbo and the wastegate and blowoff valve going off.

Damn! lightningdriver you have all those cars and you are still dropping in 20K+ into your STi.
